How often does Prosper increase credit limits?

I'm curious about how often Prosper, a popular peer-to-peer lending platform, increases credit limits for its borrowers. As someone interested in investing or borrowing on the platform, it's important to understand the factors that can influence credit limit adjustments and how frequently they occur. Does Prosper have a set schedule for reviewing and potentially increasing credit limits, or is it a more fluid process based on individual borrower performance and other factors? Understanding this can help borrowers manage their finances and investors make informed decisions about their investments.
